Large constant temperature laboratories are widely used in large or large-scale industrial products such as electronics, optoelectronics, electrical appliances, automobiles, LED lights, rubber, photovoltaic, plastics, semiconductors, aerospace and communications equipment for low temperature environmental testing. To assess whether the parameters such as reliability and stability of the tested product are qualified.
Simple parameters of a large constant temperature laboratory:
Temperature and humidity control method: Balanced temperature and humidity control method (BTHC) Intelligent PID adjustment ( with Korean or Japanese full-touch controller, which can be switched between Chinese and English ℃ (100 ℃), B: -20°C~80°C (100°C), C: -40°C~80°C (100 °C), -60°C~80°C (100°C ); -70°C~~80°C (100°C) ;
Customized volume size selectable: width, height and depth can by the user at willcan be determined, and the volume is conserved according to the dimensions width, height and depth.
Humidity range: 20% - 95% RH (humidification function may or may not be required, or high and low temperature test function can be performed without humidification if necessary)
Temperature and humidity uniformity the chamber: ±2 °C; ±4.0% relative humidity
Temperature and humidity control accuracy: ±0.2°C; ±2.5%RH
Temperature variation: ±0.5°C
Controller Analysis Accuracy: 0.01%℃, ±1%RH
Heating rate: 20℃ to 100℃ (within 60 minutes)
Cooling rate: 20℃ to -70°C, -60°C, -40°C, -20°C , 0 °C (within 100 or 90 or 60 or 40 or 30 minutes)
Inner body material: SUS304 stainless steel
Shell material: Plastic steel sheet
Insulation material: ultrafine glass wool + polyurethane foam
KCooling method: mechanical binary cooling method
Refrigerator: hermetic (French Taikang or German Copeland) compressotr
